Description:
The functions of the analog inputs are defined in those parameters.
When the option 0 (Speed Reference) is selected, the analog inputs are able to supply the reference for the motor, subject
to the specified limits (P0133 and P0134) and to the ramp action (P0100 to P0103). Therefore, it is also necessary to
configure the parameters P0221 and/or P0222, selecting the use of the desired analog input (For more details refer to
the description of those parameters in the
Section 13.2 LOCAL AND REMOTE COMMAND on page 13-29 and to the
Figure 13.8 on page 13-33 in this manual).
The option 1 (No Ramp Reference – valid only for the vector mode) is used generally as an additional
reference signal, for instance in applications using a dancer (Refer to the Figure 13.8 on page 13-33 , option without
acceleration and deceleration ramp).
The option 2 (Maximum Torque Current) makes it possible that the forward and reverse torque current limit
control be done by means of the selected analog input. In this case P0169 and P0170 are not used.
The adjustment done at the analog input AI1, AI2, AI3 or AI4 can be monitored via parameters P0018, P0019,
P0020 or P0021 respectively, The value presented at this parameter will be the maximum torque current expressed
as a percentage of the motor rated current (P0401). The indication range will be from 0 to 200 %. When the analog
input is equal to 10 V (maximum), the corresponding monitoring parameter will show 200 %, and the value of the
maximum forward and reverse torque current will be 200 %.
